One may dispute these figures and the assumptions underlying them, but for our purposes what is important is the illustration of how much variation there is among countries in the extent to which the population of the rural "reservoir" is drawn upon. It is noteworthy that the two most urbanized and advanced countries, Chile and Argentina, have one fourth or more of their total 1950 base rural population removed to urban areas within the decade, whereas Guatemala, the most backward of the seven countries, has by far the lowest-a suspiciously low—figure. As we shall soon see, migration is age-concentrated, so the actual loss in the young adult years is considerably greater than the figures indicate. However, the concept of a migratory "reservoir" is important for any consideration of migrant selectivity. Independent of the characteristics of the migrants, such as education or occupation, it is apparent that the situation in countries such as Chile, in which up to one half of the young adult population leave, does not permit the degree of selectivity that could, though not necessarily would, characterize a country where only 10 percent of the same age group migrated to cities. This important point will be taken up again in another context.
Out-migration from rural areas assumes various forms. Caldwell, in his rural survey, has provided us with some of the best data showing both the amount and form of rural out-migration. In Table 2 the migratory status of
